Hymenolepis is a genus containing 9 species which originate from Southern Africa. They are single-stemmed to slightly branching shrub or subshrub species which favour high altitude locations in the Greater Cape Floristic Region. They grow to between 0.6-2.5m tall, branching less and less with increasing height. One species, H. calva has a low-growing, branching habit, not usually exceeding 0.6m in height. These plants may be smooth or have star-shaped, white hairs across their surfaces, termed stellate hairs. Leaves are arranged alternately, they may be felted, mealy or smooth in texture. Leaves may be brown-gold, developing with age to greeny, grey-white colouration. Flowers are funnel-shaped, made up of many clustered, bright yellow blooms with 5 petals. They are arranged in structures called umbels. These are clusters which radiate from a central stem point, producing flowers on stalks of roughly equal length, to form a flattened or slightly rounded, horizontal surface of blooms.
